BIOTECHNOLOGY & GENETIC ANALYSIS - Essay Example This is mainly attributed to accumulation of pollutant along the path of river and hence bacterial population need to evolved catabolic capability to survive and hence more plasmid bearing bacterial population were found in second sample. Similarly most of the plasmid was found to be in size range more than 35 KB clearly indicates most of them are Conjugative plasmids as this group of plasmid has more number of genes compared to non-conjugative plasmid to carryout conjugation process and hence larger the size. Here re-suspension solution constitutes of glucose, EDTA and Tris each have its own role. Glucose provides osmotic stress and EDTA as chelating agents which binds to heavy metals and helps in disintegration of cell wall, Tris act as buffering agent and maintains pH of over all reactions to avoid any pH dependent side reaction. In this stage cell become highly fragile and some are break open. This solution is mixture of SDS and NaOH. Here NaOH provides alkaline condition which helps in cell lyses and denaturation of DNA while SDS dissolves cell wall constituents and induces extensive cell lyses. It also helps in proteins denaturation and precipitation. In this stage most of cell constituents get denatured including genomic DNA, But as plasmid is in its CCC (covalently closed circular) forms will not denatured completely and most of them remains in its native configuration. Step 4: Neutralisation Solution Here potassium acetate and acetic acid act as neutralizing agent to bring back the pH to normal. Similarly it induces the renaturation of DNA. Because of larger size most of the Genomic DNA remains denatured and mingled with proteins remains with cell debris while plasmid being smaller molecule except out to supernatant . Step 5: centrifugation at high speed; During this stage all cell derbies along with genomic DNA settled at the bottom of tube and being smaller in size plasmid remains in supernatant. Which subsequently used for further purification and transformation. Ans 3 protocol 6: Here we have two different observation 1) colonies from tube 2 grown as blue colored colonies 2) while from tube 3 there is mixture of blue and white. This can be explained as follows. In case of tube 2 there is only vector pGEM3Z used for transformation. The plasmid pGEM3Z have lacZ gene as marker which code for enzyme called beta glycosidase. After transformation cells where plated on LA supplemented with X-gal and IPTG. Now in presence of IPTG expression of lac Z induces and leads to synthesis of beta-glycosidase which subsequently acts on X-gal and cleaved it to chromogenic intermediate give rise to blue color. While in case of tube 3 there was plasmid vector along with insert gene (ligation mixture) and plated on similar plate after transformation. As vector pGEM3Z having MCS (multiple cloning sites) in side the lacZ gene any insertion or recombination leads to inactivation of lacZ (insertional inactivation). Inactive lacZ will not code for functional beta glycosidase and hence colonies having insertion give rise to white colors. In another scenario where cut plasmid re-ligated without any insertion during

International Marketing - Case Study Example Today instead of the traditional approach of 'maximizing' the profits, organizations go ahead with multiple objectives, monetary as well as non-monetary. There are short-term objectives as well as long-term ones. Strategists are supposed to prioritize all such objectives, so that there is clarity and ease of decision making in situations where there is an apparent clash of objectives. Here we'll analyse Vodafone, its strengths, comparative advantages, its weaknesses and some of the opportunities that it can capitalize on in the Turkish telecom market. Vodafone has acquired competitive advantage over its rivals on account of its marketing efforts, brand building, value creation, innovation, operational efficiencies etc. Today Vodafone is one of the world's leading international mobile telecommunications group having an equity base in 27 countries across 5 continents, 186.8 million proportionate customers and 33 partner networks (Vodafone, 2006). Company's vision statement1 says, the c ompany aspires 'to be the world's mobile communications leader, enriching customers' lives and helping individuals, businesses and communities to be more connected in a mobile world'. With this vision company plans to invest in Turkey. The PEST or PESTEL analysis is a useful tool for any industry or b... The analysis mainly comprises of; Political factors Economic factors Socio-cultural factors Technological factors Environmental Factors Legal Factors All these factors have different relevance for different types of industries and businesses. Political The modern Republic of Turkey was founded in 1923 by the legendary Mustafa Kemal, better known as "Ataturk" or father of the Turks. The democratic tradition of modern Turkey has faced quite a few challenges with periods of instability. In the recent past Turkey has also been criticized for its human rights record. Amnesty International accused the Turkish government in November 2001 of systematically and regularly torturing its citizens. Corruption remains one of the key challenges for Turkey. After the parliamentary elections held in November 2002, the Justice and Development Party (AKP), a moderate Islamist group, won a resounding majority. This caused some worry amongst the proponents of Turkey's reforms program, as AKP is known to position itself as a champion of Turkey's beleaguered impoverished majority, and is therefore potentially vulnerable to damaging economic populism (Datamonitor, 2006). But so far all such apprehensions have been put to rest with the continuance of the e conomic reforms, a necessity for favorable investment climate in the country. Turkey has been successfully able to overcome the banking and currency crisis of 2000-2001 Economic Turkish economy was in real bad shape during the 1990s, with growth rates of about 3% only. The 2000-01 banking and currency crisis further crippled the economy. But with some active support from IMF, the economy has been able to stage a turnaround. Owing to successful economic and structural reforms, CAGR of the Turkish economy over 2000-2005

How shift work impacts the health of employees

How shift work impacts the health of employees (Johnson 1999). Shift work is defined as the system where the people work on the regular bases based on shifts, these shifts are divided into three blocks they are morning shift, afternoon shift and night shifts. Work shift show complications in the schedule of family lifes activities, and negative health effects. (Halpern,2005; Levin-Epstein, 2006; Rosa and Colligan, 1997; Coasta, 2003). Shift workers are defined as anything other than normal day time timetable. These may includes evening work, night rotation, split shift, causal or on call job and irregular shifts. Work life differences affect full time workers (Williams, 2008). Shift work system leads to many physiological and psychosocial problems which affect the health of the individuals workers. (e.g., Nachreiner et al. 1995, Costa 1996), Physical health variables include gastrointestinal problems, sleep problems and psycho vegetative. (Akerstedt, 1985) employees who work fixed shifts will show less physical health problems co mpared to rotating shift employee in rotating shifts report more physical health complaints than those with fixed shifts . According to Basner (2005), about 20% of the employers at the workplace do work in shifts. Therefore, in that the case it is seen that the shift work does effect the routine system of the person as a whole. It affects the abdominal system and does effect in psychological terms too. According to McCall (2004), did a study on the employees of the hospital and they found that their life is on risk while working on shift work and increases the severity of occurrence of problems and the Oregons working data came out on the conclusion that the workers who were doing night and evening shifts were on more risk than those working on day shifts. Serious health risk factor occurs due to circadian rhythm disturbed in shift workers. Main reason for shift work is due to the nature of the job, occupational services such as nurses, doctors, and police officers are related with shift works. (Smith and Ward, 1986) The three prominently identified associates of experienced stress are: Alcohol use, family problems, self-reported medical maladies by Military police. (Spring, 1980) men working different shifts are likely to take heavy drinks some digestive supports on regular basis, where as women working in different shifts take tranquilizers and sleeping pills on regular bases to reduce stress problems. Both men and women working variable shifts show emotional efforts. Employees who are working night shifts are mostly exposed to the breast cancers.(Schernhammer et al. 2003) suggest that employees who are working rotating night shift for 3 days in a month for more than 15 years shows colorectal cancer in women. Circadian rhythm desynch ronisation, the disruption of the bodys biological rhythm has been a significant factor in explaining shift works effects on health, (Moore-Ede at al. 1962). The actuality that shift work disrupts eating, sleeping working patterns is a cause for concern. In his studies , Halberg (1959) the term circadian rhythms which has been used to explain the various bodily functions over the 24 hour cycle, (Harrington, 1978). Our bodies follow a natural rhythm and a vast research has been done in this field. A general survey conducted in the 2005 states that about 45% of people working belongs to health occupational field. (Folkard, 1996) shift workers that do hard jobs will need to actually relax, this is called desynchronization. Health-related risk factors occur due to the disturbance circadian rhythmic connection to the shift works. It is important to note that employees who stop doing the shift work show more health problem compared to present shift workers (Frese and Semmer 1986). Social problem and family problems are observed in shift workers; these problems diminish by day to day life activities such as their childrens education, they spend less time with their families as a effect of shift work, And also decrease in the spouse pleasure (Smith and Folkard, 1993), researches are opposing studies on work-nonworking argument with rotating shifts among workers (Bohle and Tilley 1989). Some of the findings of other research show that employees working shifts show difficulty in utiliz ing the potential of spare time (Baer et al. (1981, 1985). The effect of shift work may be due to shifts rotation so ignoring working evening hours or weakened hours will improve the physical and psychological well being of these workers (Monk and Folkard 1985). The studies have also found that the rotation shifts and positive attitude at the work place have been greatly linked. Those who are working on the rotation shift have the positive job attitude. Positive job attitude behavior is less in Rotating shift workers i.e. Organizational commitment, and job satisfaction, compared to fixed shift workers, some of the other research finding states that fixed shift works show less favorable job approach compared to Rotating shift workers (Jamal 1981). The central research states that working in socially rotating shift or fixed shifts i.e. evening and weekends show different increased levels of burnout, home conflict, and negative job attitudes such as turnover intentions, commitments, organization, and job satisfaction. And also show absence and impaired general health. These central research studies mainly focus on rotating vs. fixed shifts and working hours evening, day time and weekends. To minimize health risk by shift work much can be done such as employers can make sure that there is enough time for employees to have health food at right time, best way to achieve this is to provide microwave so that employees can bring healthy food and have a place to heat their food during meal time and also employers can put in place and open lunch system whereby given who are on 12 hrs shift. The opportunities have a tea break, and lunch break each time which is necessary such effects helps to reduce the risk of getting gastro intestinal disorders. CONCLUSION: For shift work, in order to minimize the overall risk on a shift schedule, we need to consider the provision of breaks within them, number of successive, and the length of shift work. Furthermore, it is clear that these factors need to be considered in mixture with one another since for example, a 12 hour shift work includes regular rest breaks which prove to be safer than the usual 8 hour night shift with just a lone break.

Critically review the evidence that work-life conflict leads to negative health outcomes Greenhaus Beutell., (1985). Defined as Bi-directional relation between work and family life. It is the form of inter -role conflict in which pressure from both family and work are mismatched. Work and family has two direction of conflict. There are two types of conflicts observed i.e. Family-to-work conflict and work-to family conflict, Family-to-work conflict takes place when the work combines with family life (Example-parents may take leave to attain the family function), in the same way Work-to-family conflict occurs when work interfere with family life activities. (For example unexpected meeting from the higher officials may stop the person from picking up of the children). (Frone, Russell, Cooper, 1992; Kinnunen Mauno, 1998) employees are more focus on work-to-family conflict then the family-to-work conflict. (Allen et al., 2000; Byron,2005). Conflict on work-life shows negative health results such as job attitude and impaired health, due to this effects vast research has been done directly on work-family problem and its results. Person when performing different roles in his life at a time is called overload, but these people show different attitude in the home and office permissions. Work load and increased working hours leads to many negative outcomes like (Burke Green glass, 1999; Phillips-Miller, Campbell, Morrison, 2000) decreased job performance, reduce job satisfaction (Allen, 2001).it also show psychological problems like anxiety, poor physical health, depression, increased level of alcohol use. (Frone,Russell, Cooper., 1997; Major et al., 2002). Thus these psychological problems show both direct and indirect effect on work -family relatio nships. Work -family balance were explained by three ways i.e. Time balance in which time is equally balanced with work and family ,second is involvement balance where equal involvement is required to maintain work and family and the third one is satisfaction balance were work and family is equally satisfaction. Investigations show that individuals show high quality of life when they spend more times with family then the work. Research conducted on working mothers. This study examine the families were mother and father are working according to this survey, Work-to-family show positive response to life satisfaction, job satisfaction and negative response to individual stress. Family-to-work show positive response to family satisfaction, life satisfaction, and marital satisfaction. But show negative effect organizational commitments. In this study it explains that father works more than 49 hours in a week and spends most of the time in the house hold matters where as mothers works less compared to father and show less involvement in the house matters i.e. they work only 46 hours in a week. However father show less work-family conflict, greater family satisfaction, marital satisfaction and less individual stress and more life satisfaction compared to working mothers. A Study conducted was conducted by Portuguese university students .these people interview and collected the data from in depth 32 interviews from different back ground. Finding of these study shows that worries are mainly felt by the mother particularly children dependent mother. The data also proposed that work-family procedure are unsuccessful if they are not supported by a positive work-family background. (Cooper and Quick,1999). Work life conflict may leads to undeveloped performance which is difficult to face to the confronts, rewards and chances. Working may result in poor inspiration, poor efficiency, and poor person growth; this state is called as qualitative under load. This under load stress may result complicated stresses and health problems. Some of the examples which enter in to daily life are changes in the job performance, lack of endorsement and concentration and from the officials, cold and warm clashes with generation, difficulty in implementing the new group structure and working on computer programs. All this situations may affect health and well being of the individuals as well as organisation. Examples which leads to conflicts in case of organization (Cooper, 1999) are: if there is change in employee and organizational relationship, change in the products, production and in technology department side. The current rate of place and change have accelerated in the past few decades. In the present global scenario, the need to be globally competitive in order for economies to stay afloat and sustain growth, significant burden is placed on the drivers of growth; these are the individuals at large. This huge strain on individuals and organizations has led to some degree of family breakdown. It is strange and ironic to view workplace as a source of money and comforts on one hand, on the other hand as a source of stress, depression and health related problems. (Higgins and Duxbury: 2002). According to Bachmann, 2002 there is an established correlation between a satisfied, committed, motivated, individuals and health and well being. Over 5 million people in the UK have asthma, suggesting upwards of 75000 could have work related asthma ,worsened by work.38,000 people have work related skin problems that are manifested in the form of eczema and contact dermatitis. NHS figures are staggeringly high in terms of GP visits annually. Stress related financial costs are something to the tune of 12 billion pounds annually. This mounting evidence ought to compel government, policy makers, trade unions, researchers and various organizations to join hands and formulate policies in favor of family friendly working style that could to some degree alleviate some issues. Conclusion: Work-life conflict both in family and organization leads the individuals to many physical and physiological problems to avoid these problems individuals should learn some professional skills like working teams, dealing with group thinkings, facing bullying situations, learning how to manage the stress conditions, developing the skills to reach the goals. And gain knowledge which is essential to keep the individuals to work without undergoing stress.

Discuss and critically evaluate research that has examined the impact of bullying at work Workplace bulling research began in Sweden in the 1980s. Research from both countries like Finland (Bjorkquist et al, 1994) and Norway (Adams and Crawford, 1992) conducted studies on work harassment and mobbling.Andrea Adam 1990, a British Freelances journalist brought the phenomenon bulling this leads to develop numbers of researches by UK scholars. According to (Baron Neuman, 1996; Einarsen Matthiesen, Skogstad, 1998; Keashly, 1998). Workplace bullying is defined as a persistent and continuous pattern of abuse of work and negative events directed at workers. Bullying is a form of coercive interpersonal power. It involves intentional impose of injuries, verbal abuse, exclusion and repeated physical contact, offensive teasing, isolation, social exclusion other negative actions. (Forsyth,2006). Due to this situation the target finds difficult to him or her or to face the situation. These situations may leads to severe mental, physical and psychological disease. Bullying in everyday life may cause humiliation and harm if it occurs on regular basis. Many researches also showed that large amount of money is wasted due to destructive conflict and bulling at work. Surveys among some 8,000 Norwegian employees, 54 per cent of the victims reported that bullying is done by a superior (Einarsen and Skogstad, 1996). Supervisors and managers are seen as the bullies in many cases, this is due to power differences in the parties. (Zapf, in press) In English, Austrian, German, studies states that between 70 and 80 per cent are bullied by a superior. Victims who suffered by the supervisors seems to face more psychological problems compared to victims of co-worker. (Einarsen and Raknes, 1997a; 1997b) Leymann (1993) interviewed victim and stated that there are four factors responsible for eliciting harassment at work. Deficiencies in work design, a low moral standard in the department a socially exposed position of the victim, and deficiencies in leadership behaviour (Randall, 2001) Individuals are deeply ashamed of being maltreated and are at their bewildered at their obvious failure to protect themselves and fight back.(Bernardi 2001, Strawbridge 2001) workplace bulling leads to many consequences like the individuals show less productivity they may also suffer from trauma related illness and also they are great risk at self harming behaviour due to this situations some individuals may quite the job without thinking that they do not have new job. According to Layman (1990), the term bullying was used without giving the term of schoolyard and this was for the very first time used in about 1990. There have been many studies which says that bullying have been a top most thing to spread all over the world in many countries and about 3% of the population from Scandinavia effected because of bullying at the work place (Einarsen and Skogstad, 1996; Layman, 1992). According to Hoel (1996), the students from United Kingdom have also been at the top that show the rate of bullying of around 10%. According to Mikkelson and Einarsen (2002), a psychological variable such as fear, anxiety, and helplessness has been found to be the cause of the psychological harm by the person. These variables do effect the job satisfaction and commitment and person do inclined low towards the job. According to Cooper et al., (2003), did a study on 674 males and 981 females who were working in the hospitals and studied the correlation between the work-place bullying and how health affected their job. The participants reported the increased rates of leave and sickness and also increase in absent rate. The participants also reported the effect on the mental and physical health. Quine, 1999; edition, 2001 hunt, 2001) bulling in medical setting will give rare insights of health professionals. The practices can be studied under two categories i.e. hierarchical workplace bulling horizontal workplace bulling. Horizontal workplace bulling is related to nursing (Duffs, 1995, Lee 2001 Strawbridge 2001; Hocking 2002) and these publications states that workplace bulling occurs between professionals and workers will show some levels of bulling in the same field. In Britain, study conducted on NHS community trust and reported that 38% of employees working in health sectors experiences bulling at work in the previous years .Some study reported that 37% of 594 junior doctors was bullied in past year (Quine, 2002), medical students in United States suffer high level of job related bulling during their training period. (Daughters, Baldwin and Rouley, 1998. Kassebaum and Luttes, 1980). The other form of bulling at work is the sexual harassment may reduce productivity, increase stress, decreasing commitments and threatened by the individuals may occur. Criminal justice public order act 1994 says about harassment the other form of bulling at work is sexual harassment where male domination is more ranges from serious rape to less serious but understanding behaviors such as sexual jokes. Australian medical students experiences high level of bulling during their medical training but they named these bulling as sexual harassment (White, 2001).Combination of increasing competition economic rationalism, downsizing, dynamic, Macho management styles have created a culture where bulling can be removed or thrive. (Besag, 1989) for several years research has been done on bulling at schools and he states that it is stable phenomenon. United Kingdom shows high incidences of bulling in schools (Butch Knoff, 1994), his research also states that all students show bulling at their study level. Survey conducted on part time students at Startfordshire University i.e. 1137 samples and they also asked the worst working situation where they were bullied. Then they answered that 53% were bullied at some point in their working period, and among them 19% were singled victimized and remaining were bullied in groups.(Coyne et al., 2000), Bullying results in a ripple outcome signifying that the occurrence do not engage just a few troubled employees, but instead it is an active process that negatively affects everyone in the work setting. In bullying work atmosphere non exposed workers will show less negative experiences compared to exposed workers .worker that are exposed to bullying conditions will show more stress and mental problems than non-exposed workers (Vartia, 2001, p. 65).Many research proposed that bullying show negative impacts on work quality results. (Rayner et al., 2002, p. 56)Additionally, co-workers who see their colleagues abused more often leave their jobs as a result of their contact with bullying than non-exposed workers. Conclusion: Bulling is regarded as obsessive and compulsive behaviour. Due to this bulling effect there will be low self esteem low self confidence, In order to eliminate bullying at work, organizations need to take steps against elimination of bullying otherwise it affects morale and effectiveness of employee (Randall, 1997). It is important to speak with someone who solves the problem informally like trade union official or human resources department otherwise manages or supervisor some employees are specially trained to solve harassment problems they are called harassment advisers to face problems they are called harassment advisers to face problem at work in ordered to get good output.

Drawing on recent research, compare and contrast the effectiveness of primary and secondary/tertiary stress management strategies in improving employee wellbeing. The stress in relation to work is a significant and is considered an important barrier for a variable such as job satisfaction and also to act better in psychosocial activities. According to Cox et al (2002), about 60% of the people are losing their job and not going to work because of the stress. According to the statistics of European foundation (2000), shows that there are 15% of employees complains about the headache, 25% of them indicate the symptoms of pains in neck and shoulders, 23% cases because of fatigue, 28% cause because of stress and 33% because of backache. Also, an employee assistance programmers laid an importance to provide the counseling to the employees who are suffering from stress or have difficulties related to the work-life balance and problems related to alcohol and drug intake. According to Jones et al. (1998), a survey being done in UK, showed that about 27% of the workers suffered from psychological problems such as anxiety and depression, and also stress caused many people to give up their jobs and about 20 working days were lost. In an another survey by US called as National health interview survey, found out that about millions of employees suffer from mental stress at their work place which effect their health. According to Antai-Otong (2001), stress effected and added few more problems such as burnout, other chronic problems which ultimately affected their job performance and lower down the productivity and also, lowering down their morale. The literature has also shown many longitudinal studies been done on intervention of stress management at workplace, therefore literature also talked about the cross sectional studies but could not successfully tackle out the issues and also long lasting effect of the interventions could not be seen. The stress management interventions fall under three categories which are: primary intervention, secondary intervention and finally tertiary intervention. The primary intervention aim at the redesigning, changing the work systems and changing the entire structure of organization. Therefore, it aims at primarily removing the stressor or the thing that cause to create the stress at the work place. The intervention at the primary level facilitates and increases the control over the job and also the environment at their work place and also this in turn reduces the stressors, therefore by increasing the satisfaction of the workers and their well being too. This all includes giving the proper and good working hours and the shifts patterns, and also the description of the role should be clear enough so that no stress can be laid upon the workers. According to Lazarus (2000), the primary interventions are related to the copying strategies which are problem focused and therefore reduces the causes and different sources of stress. The next intervention called secondary intervention aims at modifying the stressors which are expected or predicted and causes stress at work place. The secondary intervention, unlike primary deals with the experiences related to the stress and not by stress, as a word, for example, the coping such as emotional focused aims at reducing the emotional state related to the stress at the work place and minimizing and reducing the stressor from the person, who is experiencing the stress. Apart from this, the secondary intervention involves stress management training, social support, biofeedback etc. According to Allen et al (1999) explored and stated that experience does matter and that help in helping new employees and feel them comfortable so that they may not feel the stress at high level and thus encourage socialization. Also, a correlation was calculated and it was seen that there was a negative correlation between the socialization and stress at work. Therefore, we can say that supp ort and relationship between colleagues and peer relation at work place is so important. Social support is therefore important by making contacts with people who are directly or indirectly related to their work place. Jones et al., (2000) did a study in the hospitals to see the impact of the stress management on the employers. These programs helped to improve the skills to cope with the stress and other relaxation techniques were also used. Thereafter, it was also seen that after couple of months, there was a fall in the medication. Then thereafter, a follow up was taken for 2 years and less negligence was seen after the program of stress management was undertaken. The third and the final intervention is the tertiary intervention. According to Quick et al., (1997), tertiary interventions includes the programs such as counseling, psychotherapy and employee assistant programs As discussed at the starting various programs, employee assistance programs (EAP) has been used to tackle the behaviour which are injurious to health such as alcohol intake or problems related to drug intake, however EAPs have been successful with such patients. Sadri (1991) found in the study that the progress has been seen among the employees by enhancing their self esteem and progress have been found in their mental health state. More studies have been found that have seen that more interventions of stress management. Murphy (1996) did a review on the stress management intervention among the employers at their work place such as B.P., anxiety and other psychological problems. The techniques such as cognitive behavioral techniques, meditation, biofeedback and other strategies were reviewed, whereas meditation showed a positive and consistent results but it is hardly used in the organizations. Techniques such as cognitive behavioral strategies and relaxation reported to be successful. Also, there was a consistent and positive result among the various techniques altogether, therefore, their combination proved to be more effective than using any single strategy. Therefore, according to Quick et al., (1997), it would be suitable to say that primary interventions are the most convenient and best method of intervention because they are actively involved in eliminating the causes of stress, but secondary and tertiary approaches do help in stress management but they are only limited in removing the sources of stress but not the stress itself and this is where primary intervention plays an important role in eliminating the stress itself.

Value of Color and Light in Henrik Ibsens Wild Duck :: Henrik Ibsen Wild Duck Essays

The Value of Color and Light in Henrik Ibsen's Wild Duck    In the Wild Duck, Henrik Ibsen begins his play by emphasizing the value of color and light. He uses the theme of light to contrast Old Werle, a stingy rich man, with Old Ekdal, a poor helpless man. Ibsen connects the color green with the loss of eyesight of Old Werle. A possible affair between Old Werle and Gina, Hedvig's mother, may suggest the cause of Hedvig's loss of sight. By using sun and moon, Ibsen establishes the atmosphere of the scene. The story line deteriorates from peaceful to tragic. Similarly, does the setting in the last four acts. In the Wild Duck, Henrik Ibsen employs the image of light to portray certain characteristics in order to construct the plot and to adjust the mood of the scene. F.L. Lucas analyzes the opening arrangement and writes "In the outer room the lamps are dimmed, with green shades, in contrast to the brilliance of the room behind"(190). We understand that this meant that the outer room, lit with soft and shaded light, implies poverty, where as th e inner room, illuminated with bright candles, expresses wealth. The darkened room, insinuating poverty, is the office in which the poor Old Ekdal 'does some extra copying,' and in return receives a small income. The inside room, representing wealth, is Old Werle's dining room where he was hosting a party. The distinctions of these two lit rooms contrast Old Ekdal and Old Werle. "In contrast to Werle's party, the lighting is of comparative poverty 'on the table a lighted lamp'"(190), explains critic, F.L. Lucas. Unlike Old Werle's expensive and exquisite illumination, a small inexpensive lamp lights the Ekdals home, displaying poverty. This dissimilarity shows another significant distinction between Old Werle and Old Ekdal. The distinctions of the light between Old Ekdal's and Old Werle's homes is illustrated in the following incident.It is brought to the reader's attention that in the following quotation Old Werle and Old Ekdal were partners in crime. "[Old Werle] escaped by the sk in of his teeth," while they sentenced Old Ekdal to prison. This incident resulted in extreme hatred toward Old Werle for his poor aid to Old Ekdal. Being that Werle had a vast amount of money, Old Ekdal, Hjalmar, and Werle's son, Gregers felt tremendous feelings of animosity. Gregers recognized the miserable support his father has given to the Ekdals.

Effects of Silane Based QAC on Hygienic Unifrom Fabrics

Consequence OF SILANE BASED QAC ON HYGIENIC UNIFORM FABRICS ; IT’S EFFICACY AGAINST HUMAN PATHOGENIC BACTERIUM BY BIO-BURDEN Trial Abstraction The demands for unvarying cloths are under different industrial environment, supplying attention, freshness, comfort and protection for the tegument. The survey besides saw types and consequence of bug every bit good as chemicals used to protect the unvarying cloths against their onslaught under the environment of different corporate industries, so they can populate in a more fresh and hygienic ambiance. The intervention withzycrobial( Silane based QAC ) besides improves the antimicrobic consequence of cotton, p/v and p/c cloth measured by BPB discoloration trial compared to untreated cloth.Zycrobialtreated aprons were exposed to different environment and evaluated by bio-burden trial which is new trial method in fabric testing. The treated aprons shows low bacterial tonss in different industrial environment compared to the untreated 1s. Cardinal Footings Uniform cloths, Antibacterial Efficacy, Bio-burden trial, Silane based QAC, Zycrobial, BPB trial. Introduction Fabric consumers all around the universe are now going much more cognizant of the hurtful effects, that microorganism may hold upon fabrics and up on human hygiene. Fabrics are one of the chief bacteriums transporting medium. Textile fibres provide the perfect platform for growing of micro-organisms. Even the different environments ( hot, humid, and cold ) lead to growing of different bacteriums. These bacteria/microbes on fabrics frequently result in staining, decolouring of the cloth and leads to bad smell1-6. In India, the usage of antimicrobic fabrics is become premier necessity due to the worm and humid clime. This is the most suited environment for the growing of micro-organisms. Clothing and fabric stuffs are the bearers of these micro-organisms such as infective bacteriums, odour bring forthing bacteriums and mould fungi, besides become good media for their growing7-10. Microbial infestation airss danger to both life and non life affairs. Obnoxious odor organize the interior garments such as socks, spread of diseases, staining and debasement of fabrics are some of the damaging effects of bad bugs. Though the usage of disinfectants have been known for the decennaries, it is merely in the recent twosome of old ages several efforts have been made on completing fabrics with antimicrobic compounds11-20. Antimicrobial coating is a recent invention in coatings. The consumers are now progressively cognizant of the hygienic life manner and there is a necessity and outlook for a broad scope of fabric merchandises finished with antimicrobic belongingss21-25. This finish prevents the growing of bacteriums and merchandises finished in it have been proved environment friendly and wellness protecting, forestalling diseases. It besides prevents garments from unpleasant smell26-36. Zycrobialis one of the merchandise ofZydex industries.Zycrobialis recollective, non flammable, non leachable, easy to use organo-functional silane based antibacterial. It provides lasting anti-bacterial and anti-odor coating and ensures freshness and comfort for the user. This recollective coating is covalent adhering to hydroxyl group ( in instance of cellulose fiber ) and/or by formation of permeating polymer concatenation around the surface of fibers ( in instance of man-made fiber ) .Zycrobialexpeditiously inhibits growing of bacteriums and thereby protects fabric merchandises from impairment and stain. It is for good fixed to the substrate by proper drying or hardening. It has user-friendly glycol as against methyl alcohol in other similar viing merchandises. It is eco friendly and safe for usage by human existences. The experimental program was based on application ofzycrobial( Antimicrobial agent ) on polyester/viscose, polyester/cotton blend and 100 % cotton cloth by pad–dry-cure method. The treated cloth was check silane based QAC compound presence by BPB ( Bromo Phenol Blue ) trial in footings of alteration in their microbiological activity. The efficaciousness of the intervention was besides evaluated for its efficaciousness against 30 wash harmonizing to the standard method. This omegaycrobialmerchandise was besides applied to industrial apron that is polyester/viscose blend uniform cloth by exhaust method. These aprons were exposed in different environment like milk industry, nutrient fabrication, infirmary, infective lab, etc. and collected after 3 to 6 yearss, eventually tested for its antibacterial efficiency by Bio-Burden Test. Materials Fabrics The three types of cloths were selected for unvarying cloths viz. , Polyester/Viscose ( P/V ) , Polyester/Cotton ( P/C ) blend and 100 % Cotton ( C ) . The item specifications for cloths are given in Table I.

Looking to the environmental protocol today’s universe requires an eco-friendly and cost effectual manner to complete fabrics. Therefore in the present survey omegaycrobialas antibacterial coating agent was selected and this is eco-friendly in nature.Acetic acid( CH3COOH ) was used in thezycrobialintervention bath for keeping Acidic pH. TheR-77was supplied by zydex industries and used as pretreatment of all cloths withSodium carbonate( Sodium2Carbon monoxide3) . TheECEmention detergent was used for BS EN 26330:1994 domestic rinsing method. All chemicals used in this experiment were of analytical class and used without farther purification. Experimental methods Preparation of fabric cloths for intervention To take the coating and other hydrophobic drosss from all the three selected cloths. The cloths were treated with the bath incorporating 5 gpl non-ionic detergent ( R-77 ) and 2 gpl Na carbonate for 30 proceedingss at 800C temperature. The cloths were so washed exhaustively in running H2O, neutralized, washed once more in running H2O and eventually dried under shadiness. The pretreatment procedure was carried out in L.G. Direct Drive rinsing Machine. The pH of cloths was checked to impersonal before farther processing. Application of Zycrobial on Fabric by Embroidering Technique Application ofzycrobialon cloth was done by embroidering technique. In pad application, the cloth immersed in spirits contain needed sum of antimicrobic agent (zycrobial– 30 gpl ) and pass through the cushioning mangle at 2.5 kg/cm2force per unit area utilizing laboratory two bowl embroidering mangle. The cloth was later dried and cured at room temperature. Application of Zycrobial on Aprons by Exhaust Technique In exhaust application, the unvarying garments were treated with 3 % and 5 % ( owf )zycrobialfor 20 proceedingss at room temperature maintaining the Liquor ratio 1:10. The 5 % ( owf ) was done on infirmary and pathology lab aprons and 3 % ( owf ) for other aprons. The intervention was performed in rinsing machine utilizing exhaustion technique of application. Finally, the samples were dried at room temperature under shadiness. Washing procedure The lastingness of thezycrobialintervention was evaluated by BS EN 26330:1994 method utilizing domestic lavation procedure. The specimen was washed in an automatic domestic lavation machine by utilizing 1 gpl ECE detergent at 400C for 30 proceedingss and line dried at room temperature harmonizing to specified process. The procedure was repeated for 30 times utilizing the same process of rinsing. After 30 wash, the samples were tested for their efficaciousness by BPB trial. Evaluation of Treatment for Antibacterial Activity of Textiles Antibacterial efficiency of fabrics was measured by two methods:Bromo phenol blue method ( BPB-Stain Test )Bio-Burden TrialEvaluation of antimicrobic activity by BPB methods Testing of white or light- colored goods:Bromophonol Blue ( BPB ) solution of 0.025 % was prepared in distilled H2O ; few beads of saturated Na2Carbon monoxide3solution per 100 milliliter BPB solutions was add.10 milliliter of the solution was taken in beaker and the trial specimen was soaked in the solution for 20 mins. Finally the sample was rinsed in distilled H2O.The sample was observed for the blue discoloration and comparison against Bramophenol Blue colour trial graduated table.Evaluation of antibacterial efficiency by Bio-Burden trial Bio-burden is new trial method for proving antimicrobic activity of fabric. Bio-burden is usually defined as the figure of bacteriums populating on a surface ( Textile, Food, etc. ) that has non been sterilized. The term is most frequently used in the context of bio-burden testing, besides known as microbic bound testing, which is performed on pharmaceutical merchandises, medical merchandises and membrane filtration for quality control purposes. Merchandises or constituents used in the pharmaceutical or medical field require control of microbic degrees during processing and handling. Bio-burden or microbic bound proving on these merchandises proves that these demands have been met. The population of feasible micro-organisms ( bio-burden ) in a merchandise or on a merchandise surface is required to supervise a production procedure, be it for a medicative merchandise or a medical device. In most instances, with a medicative merchandise one is analyzing the merchandise straight, in which instance there is a demand to do certain there are no antimicrobic belongingss in the merchandise to impact the consequences. This is usually done by micro-organism recovery experiments. In the instance of medical devices there is the possibility that the extraction process may non take all the micro-organism from the device, thereby doing an underestimate of the existent bio-burden nowadays. These are based upon the standard ISO 11737:127-28. Bacteriological surveies of efficaciousness of the antibacterial activity on treated and untreated uniform garments after usage were following stairss:Two sets of treated and untreated aprons ( Shown in Table II ) were distributed for usage in different environmental scenes likeHospitalpathology research labMilk merchandise millFood processing unitGeneral Chemical Laboratory.Table II.Detailss of the aprons exposed in the different environmentSr.No.Treated/UntreatedDescription of EnvironmentDayss to Expose1TreatedDairy- ( Butter, Milk )6UntreatedDairy- ( Butter, Milk )62TreatedDairy- ( Paneer, Ice pick )6UntreatedDairy- ( Paneer, Ice pick )63TreatedRestaurant3UntreatedRestaurant34TreatedBakery3UntreatedBakery35TreatedGeneral Env.

From the consequences, it can be seen that the samples treated withzycrobialexhibited good antimicrobic belongings compared to untreated samples as per BPB discoloration graduated table. Efficiency of the intervention was found decreased by increased in figure of rinsing rhythm. The consequence shown in Table III revels that after 30 wash, the deepness of bluish coloring material discoloration become lighter thanzycrobialtreated samples without wash. Further, the cotton samples withzycrobialintervention shows somewhat darker coloring material even after 30 washes. The treated samples shows darker blue discoloration compared to their untreated opposite number. Even after 30 washes the treated sample shows darker bluish discoloration compared to the untreated control sample. This consequence indicates that the efficiency ofzycrobialtreated samples retained antimicrobic belongings even after 30 wash.

The intervention withzycrobialbesides improves the antimicrobic consequence of cotton, p/v and p/c cloth measured by BPB discoloration trial compared to untreated cloth.Zycrobialtreated aprons were exposed to different environment and evaluated by bio-burden trial. The treated aprons shows low bacterial tonss in different industrial environment compared to the untreated 1s. It suggests that thezycrobialtreated aprons may be used routinely to minimise the transpersonal taint in the environment. Remark on study:Non haemolytic, coagulase negativestaphylococciare natural dwellers can be found on the tegument as a commensal vegetation.Bacillus subtilisis a saprophytic bacteria. It is by and large found as a contamination in the microbiology research labs.Bacillus spp.( gm positiveB aerophilic B) is seldom recovered from clinical specimens. Their clinical significance is unsure.Recognition I take this chance to show my deep sense of gratitude towardsMr. J. Sridhar ( Vice President-Textile ),Mr. P. Pandey and Ms. S.

Jim Crow Laws

Segregation and disfranchisement laws were often supported, moreover, by brutal acts of ceremonial and ritualized mob vi olence (lynchings) against southern blacks. Indeed, from 1889 to 1930, over 3,700 men and women were reported lynched in the United States–most of whom were southern blacks. Hundreds of other lynchings and acts of mob terror aimed at brutalizing blacks occurred throughout the era but went unreported in the press.Numerous race riots erupted in the Jim Crow era, usually in towns and cities and almost always in defense of segregation and white supremacy. These riots engulfed the nation from Wilmington, South Carolina, to Houston, Texas; from East St. Louis and Chicago to Tulsa, Oklahoma, in the years from 1865 to 1955. The riots usually erupted in urban areas to which southern, rural blacks had recently migrated. In the single year of 1919, at least twenty-five incidents were recorded, with numerous deaths and hundreds of people injured.So bloody was this summe r of that year that it is known as the Red Summer of 1919. The so-called Jim Crow segregation laws gained significant impetus from U. S. Supreme Court rulings in the last two decades of the nineteenth century. In 1883, the Supreme Court ruled unconstitutional the Civil Rights Act of 1875. The 1875 law stipulated: â€Å"That all persons †¦ shall be entitled to full and equal enjoyment of the ac Some historians believe that a Mr. Crow owned the slave who inspired Rice's act–thus the reason for the Jim Crow term in the lyrics.In any case, Rice incorporated the skit into his minstrel act, and by the 1850s the â€Å"Jim Crow† character had become a standard part of the minstrel show scene in America. On the eve of the Civil War, the Jim Crow idea was one of many stereotypical images of black inferiority in the popular culture of the day–along with Sambos, Coons, and Zip Dandies. The word Jim Crow became a racial slur synonymous with black, colored, or Negro in the vocabulary of many whites; and by the end of the century acts of racial discrimination toward blacks were often referred to as Jim Crow laws and practices.
